Eurocopter EC135 T2, G-IWRC

Summary:

The pilot and his passenger were returning to the UK from Europe. Whilst passing through the Stansted control zone, the helicopter had an event during which the auto trim in the Automatic Flight System disengaged and the helicopter pitched nose down. The pilot, believing he had a double engine failure, entered autorotation. During the landing flare the tail of the helicopter struck the ground first, severing the fenestron drive. The helicopter subsequently rolled on to its side and was extensively damaged. The occupants escaped without injuries.
